AAIController

class AIModule Blueprint Since 4.0

#include "AIController.h"

Description

The base controller class for AI-driven pawns. Manages a Behavior Tree, Blackboard, and perception system for autonomous NPCs.

• AAIController is created automatically when an AI pawn is spawned if AIControllerClass is set. You rarely instantiate it directly.
• GetBlackboardComponent() returns null until UseBlackboard() or RunBehaviorTree() has been called.
• AI logic only starts on possess if bStartAILogicOnPossess is true (default false).

Run a behavior tree from BeginPlay C++

void AMyAIController::BeginPlay()
{
    Super::BeginPlay();
    RunBehaviorTree(MyBehaviorTree);
}
